This error message is wrong

clojure -M -e '#uuid id'
Execution error (AssertionError) at clojure.main/main (main.java:40).
Assert failed: (string? form)

Reader error (AssertionError) at clojure.uuid/default-uuid-reader (uuid.clj:12).
Assert failed: (string? form)

Syntax error reading #uuid id at (REPL:1)
id - failed: string? at: [:form]

You don’t need anything special there - just an instrumented spec on the data reader fn

If you could drop the first on an ask question I’ll take a look later

Do you see same in the repl?
